Purpose: The purpose of this study is to examine the relationship between work personality, core self-evaluation (CSE), and perceived internal and external barriers to employment in a group of young adult CNS survivors.

Methods: The participants consisted of 110 young adult survivors of pediatric central nervous system (CNS) tumors aged between 18 and 30 years old (M = 23.05, SD = 3.

Survivors of pediatric brain tumors (PBTs) are at high risk for medical late effects, including pain. Although pain is common at PBT diagnosis and during treatment, less is known about survivors' pain after completing therapy. This study examined the prevalence and correlates of pain in long-term PBT survivors enrolled on Project REACH (Research Evaluating After Cancer Health), a cohort study of locally treated cancer survivors.

Purpose: Given the significant employment disparities for survivors of pediatric brain tumors, there is increased need to conduct vocational and career research with this group. The purpose of the present study was to construct an instrument, the Perceived Barriers Scale, that is psychometrically sound and has both clinical and research application related to career and employment issues of pediatric brain tumor survivors.

Method: The participants consisted of 110 young adult central nervous system survivors of childhood cancer aged between 18 and 30 years old (M = 23.

DNA polymerase β (pol β) fills single nucleotide gaps in DNA during base excision repair and non-homologous end-joining. Pol β must select the correct nucleotide from among a pool of four nucleotides with similar structures and properties in order to maintain genomic stability during DNA repair. Here, we use a combination of X-ray crystallography, fluorescence resonance energy transfer and nuclear magnetic resonance to show that pol β's ability to access the appropriate conformations both before and upon binding to nucleotide substrates is integral to its fidelity.

Among survivors of pediatric cancers, brain tumor survivors are comparatively at high risk for experiencing relapsed disease. However, little is known about how disease relapse affects long-term psychological functioning in this cohort. This study of 162 pediatric brain tumor survivors, now adolescents and young adults (ages 12-36), demonstrates that survivors who have experienced relapsed disease are at increased risk for symptoms of anxiety, even years after successful treatment for relapse.
